Updates in the Legacy System for BRAA and Forward Services

Dear Depositors,

Depósito Central de Valores informs its participants that starting last Monday, August 7, new access controls were added to the Legacy system for the BRAA and Forward services to improve its stability and performance.

Based on the above, it must be considered that from that date, the system has included the following:

1. Access blockage: With operation from Monday to Friday from 8:00 a.m. to 8:00 p.m.
2. IP control for access: Where the Help Desk (MAC) must be informed of the public IPs of your organization if they have not been authorized yet.

In addition, to mitigate the situations experienced over the last few days for the signature functionality in Forward contracts, we request participants to sign a maximum of 5 contracts at a time while the investigation takes place, and the problem is solved.

We regret the inconvenience caused to our participants, users of the BRAA and Forward services, and we would like to inform you that our expert team is working on solving the cause of the problem. After the service returns to normal, we will inform you through our website www.dcv.cl, or via email.

Kind regards,
DEPÓSITO CENTRAL DE VALORES S.A.,
